Does the Connector need to run in Desktop mode?
Only QuickBooks Enterprise users must run the Connector in Desktop mode. See Preliminary Setup Steps for more information.
What are the pros and cons of having the Connector in Desktop mode vs running it as a service?
Running the StarShip Online Connector as a desktop application rather than a service removes the need to manage many Windows user permissions required for the connector service to run correctly. We recommend running connectors used for Printing traffic as a Desktop application for this reason.
